Secondary DNS zone
DNS zone transfer is our main topic in this article. This is a Domain Name System term that you should know. What is its main purpose, and which are the different DNS zone transfers we will see today. Let’s begin.
DNS zone transfer – what does it mean
Zone transfer is the process of duplicating DNS information (DNS records) from the Primary DNS zone to the Secondary DNS zone. This enables you to create several copies of your DNS records on other name servers. If one of the name servers dies, you will have more availability as a result of completing the transfer. Furthermore, if you run a global website with users from all over the world and many presence locations, you will benefit from faster DNS resolution (PoPs).
Another important factor to note is that if a name server goes down for any reason, your website will not be damaged (for example, maintenance or a DDoS attack). It will stay accessible and available to your visitors.
If you administer a global website and want to speed up Domain Name System resolution, you might consider conducting a zone transfer to many Secondary zones. With this approach, you’ll be able to put your DNS data (DNS records) in numerous Points of Presence (PoP).
